mobile: Create "ms" singleton for struct osmocom_ms

Make the MS the script is associated with accessible to lua. Provide
access to IMSI and IMEI. The IMSI might not be available at the given
time and just return an empty string.

Example lua usage:

 print(osmo.ms():imsi());
 print(osmo.ms():imei());
 print(osmo.ms():shutdown_state())
 print(osmo.ms():started())

 function ms_started_cb(started)
	print("MS started", started)
 end

 function ms_shutdown_cb(old_state, new_state)
	print("MS shutdown", old_state, "->", new_state)
 end

 function sms_cb(sms, cause, valid)
	print("SMS data cb", sms, cause, valid)
	for i, v in pairs(sms) do
		print(i, v)
	end
 end
 function mm_cb(new_state, new_substate, old_substate)
	if new_state == 19 and new_substate == 1 then
		osmo.ms():sms_send_simple("1234", "21321324", "fooooooo", 23)
	end
 end
 local cbs = {
	Started=ms_started_cb,
	Shutdown=ms_shutdown_cb,
	Sms=sms_cb,
	Mm=mm_cb
 }

 timer = osmo.timeout(20, function()
    print("Timeout occurred after 20s")
 end)

 osmo.ms():register(cbs)

 # Can fail. Best to wait for state changes...
 print(osmo.ms().start())
 print(osmo.ms().stop(true))
